Argue the toss in a twisted tale of logic...

In ir/rational you complete, create and discredit arguments by selecting propositions and filling in the blanks. It's a puzzle game based on propositional logic, and a graphic adventure all in one - only here you don't so much need to escape the room as prove why you'd even want to.

- Unique, language-based argument system: formulate logical proofs to progress through the game

- Dark philosophical comedy by Tom Jubert, writer of Penumbra, Driver: San Francisco and FTL.

- 10 screens and roughly half an hour of intelligent, challenging and inventive gameplay

- Musical score by award-winning composer Mikko Tarmia

- Click to progress story
- Complete the arguments by selecting options from the drop-down menus

NB Some systems don't display all the dropdown options at once, and you have to use the arrow keys to scroll.

If you can't see the right answer, chances are you can resolve the problem with the arrow keys. Hope it's not dampened your enthusiasm!


I love the concept, but the drop down menus are terrible, the puzzles often didn't accept perfectly logical arguments that differ slightly from your template.
Also the dialog kinda felt a little condescending by patting you on the back for every frankly, pretty easy logical puzzle you solve.

I'd like to see a more polished version of this with harder puzzles and a better input method. (possibly fields to type in freely using variables predetermined by you?)

People find this review helpful!

When you are cornered in a circle, triangulate it.

Fun, but the buttons seem a bit hesitant to respond. I have to click on "continue" multiple times to move on.

Could be a great game, however the answers really need to be listed all at once or have a scroll bar.
I like the tests, the atmosphere and the story is great. Fix above mentioned and it's perfect.

I will give you 4 stars because of the combo box problem: for some combo boxes, you have to use the arrow keys to find certain options, and there is nothing indicating that you must do so. If you could add a scroll bar or a down arrow, then that would be great.

Apart from that, I found this game very interesting. Too bad that it was short. I have actually learned some of this before, but I never got the opportunity to put it to the test until now.

The story was very nice, and the atmosphere was very portal-esque. I loved how, at the end, you used different letters from different writing systems for the guide at the end instead of the standard x and y. It really added to the sense that you are being trapped here by a malevolent force. Were it not for the problem I stated at the beginning, I would have given you 5 stars.
